AT&T boasts of core ‘white box’ success in 5G, fiber push

AT&T said it has now migrated more than 52% of all of its production traffic onto next-generation “white box” core routers running on products from the likes of Broadcom and DriveNets.

The company said its move to such “open” systems has helped its aggressive 5G and fiber expansions.

“We announced the next-gen open disaggregated core routing and the next-gen open disaggregated IP edge routing platforms in 2020. And in 2022, our open, disaggregated program took a significant leap forward!” wrote Mike Satterlee, AT&T’s VP of network core infrastructure services. “In fact, it is meeting and, in many cases, exceeding our expectations.”

In a lengthy post to the company’s website, Satterlee said AT&T’s work in the space stretches back to its Domain 2.0 announcement in 2013, which involved pivoting much of its network hardware into software. More recently, AT&T has been working to shift its core routing systems from proprietary equipment supplied by a single vendor to decoupled, “open” components that can be integrated together into one switching and routing platform. “We call these open platforms ‘white box’ systems,” Satterlee wrote.

A major element of AT&T’s recent efforts stems from its 2020 agreement with startup DriveNets. “DriveNets really came in as a disruptor in the space,” Satterlee told SDxCentral this week. “They don’t sell hardware platforms. They are a software-based company and they were really the first to do this right.”
